Abstract
An apparatus (11) for dispensing individual plastic fasteners from fastener stock (13), includes a housing (27) and a hollow slotted needle (173) mounted onto said housing (27). An indexing wheel (95) is rotatably disposed within the housing (27) and advances a fastener to the rear end of the needle (173). A rocker (177) is slidably disposed within the housing and serves to move the cross-bar of the fastener in parallel with the needle bore. A plunger (179) is disposed within the housing (27) and is capable of being slidably displaced by a trigger assembly. An ejector rod (181) is fixedly mounted onto the plunger (179) and serves to push the cross-bar of the fastener out of the front of the needle (173). An indexing slide (137) separate from the rocker (177) is slidably disposed within the housing (27) and serves to rotatably advance the indexing wheel (95) after the ejector rod (181) pushes the cross-bar of the fastener out the front end of the needle (173).
